General Cleaning And Tightening - Maruyama MM92 Manual Del Propietario U Operador

COOLING FINS
Maintenance Interval
The cylinder cooling fins should be cleaned after every 50 hours of operation, or once a week, whichever comes first.
Air must flow freely around and through the cylinder cooling fins to prevent engine overheating. Leaves, grass, dirt and debris
buildup on the fins will increase the operating temperature of the engine, which can reduce engine performance and shorten
engine life.
Cooling Fin Cleaning
1. With the engine at ambient (room) temperature, remove
the four screws retaining the top cover, then remove the
top cover.
2. Clean all dirt and debris from the cooling fins and from
around the cylinder base.
3. Reinstall the top cover and tighten the knob.
Be sure to attach the grommet.
MUFFLER AND EXHAUST PORTS
Maintenance Interval
The muffler should be inspected and cleaned after
each 50 hours of use.
Muffler Maintenance
The muffler should be removed and serviced after
each one fifty (50) hours of use. At the same time,
the exhaust ports should be cleaned and
inspected. An AUTHORIZED MARUYAMA
DEALER should
be contacted for this service.
For long-term storage of the mist blower, first perform all regular maintenance procedures and needed repairs. Empty the
fuel tank. Disconnect the fuel supply line from the carburetor and depress the primer bulb until fuel stops discharging from
the fuel-return line.
Start the engine and allow it to run until it stops. Pull the starter cord a few times to remove any excess fuel from the engine.
Remove the spark plug and insert a small amount of oil into the cylinder. Slowly pull the starter cord and bring the piston to a
position closest to the spark plug hole. Re-install the spark plug. Apply a thin coating of oil to all the metal surfaces and store
the mist blower in a dry place.
